How is load peak current calculated?
The formula is: i = C (dV/dt), where C is the load capacitance, dV is the change in voltage, and dt is the change in time.
For example, if the load capacitance is 50 pF and the voltage rises from 0 to 2000 V in 60 ns, the current during the rising edge will be:
i = C (dV/dt) = (5.0 x 10-11) [(2.0 x 103) / (6.0 x 10-8)] = 1.7 A.
Peak current is supplied by capacitors in the pulser.
